Permafrost Terrain Disturbance Susceptibility in the Nacho Nyäk Tagé (Stewart River) Watershed, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

An interdisciplinary review of the interplay of conflict, socio‐economic factors, and land cover and vegetation dynamics in Colombia

PLANTS, PEOPLE, PLANET, EarlyView.
Colombia's forests play a crucial role in preserving biodiversity and mitigating climate change, but they are currently facing severe degradation, particularly after the 2016 Peace Agreement. Our literature review highlights a growing research interest in this topic and demonstrates how interdisciplinary approaches combining diverse methods can enhance

Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Patterns of Ecosystem Structure and Wildfire Carbon Combustion Across Six Ecoregions of the North American Boreal Forest

Frontiers in Forests and Global Change, 2020
Increases in fire frequency, extent, and severity are expected to strongly impact the structure and function of boreal forest ecosystems. An important function of the boreal forest is its ability to sequester and store carbon (C).

Development and adoption of Kernza—A perennial grain crop for sustainable agriculture

PLANTS, PEOPLE, PLANET, EarlyView.
Annual cereal grains account for ~50% of human food calories, but cultivation of these crops has resulted in major environmental and social issues worldwide. For nearly three decades, researchers have been breeding intermediate wheatgrass—a perennial cool‐season grass—to serve as the world's first commercial‐scale perennial grain crop to improve ...

Pyrogenic flowering of Aristida beyrichiana following 50 years of fire exclusion

Ecosphere, 2019
Fire‐stimulated or pyrogenic flowering is one of many traits that enable plants in fire‐prone ecosystems to persist or dominate following frequent fires.

Persistence and potential of soil organic carbon in nature‐based climate solutions: A review of managed disturbances

PLANTS, PEOPLE, PLANET, EarlyView.
Implementing nature‐based climate solutions is important for mitigating climate change, which is a global issue, but requires local adjustments in management practices. Using the association between soil carbon and minerals as a proxy for carbon persistence, we evaluated the effect of different management regimes on soil carbon sequestration and loss ...

Fire intensity effects on flowering and post-fire bud activity in the endemic savanna bunchgrass Aristida beyrichiana. [PDF]

Plant Biol (Stuttg)
Although flowering and bud activity are not significantly affected by fire intensity, wiregrass' bud bank changes with time since fire. Abstract The bud bank of perennial grasses is a key aspect of their reproduction and longevity in frequently burned ecosystems.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Evolving fire management strategies and their impact on the occurrence and spatial extent of unplanned wildfires in a large African savanna park

Territorium: Revista Portuguesa de riscos, prevenção e segurança, 2018
Savannas cover approximately 20 % of the global land surface. In African savannas, fire is an important agent for controlling these ecosystems. Kruger National Park (KNP) is a large African savanna park which has implemented a variety of fire management ...
